🍕 What we're MAKING today: My Pizza Recipe

In Opposite Potion you flipped rules with NOT, and in Logic Boss you combined checks with AND and OR. Today you package those rules into a FUNCTION — a reusable recipe! 🍳

What is a function? It's a named recipe. You write the steps ONCE inside function makePizza(topping) { ... }, then call it by name: makePizza("cheese"). The word in the parentheses — topping — is a parameter: an input slot. Each call can pass a different ingredient (an argument), and the SAME recipe makes a DIFFERENT pizza! Real apps do this everywhere: one sendMessage(friend) function, a million messages. One recipe, infinite pizzas! 🍕

🔗 Last time you used ! to flip a rule. Today you write function makePizza(topping) — a recipe you can call with makePizza("pepperoni") again and again. The AND/OR/NOT rules live INSIDE the function now, so every pizza you bake follows them automatically! 🍕

💡 Tap a red chip in the code to change the topping or the rule function = recipe · call = bake!

You Built the Pizza Recipe Machine!

You wrote ONE function and called it with many different toppings — one recipe, infinite pizzas! That's how every real app works: write it once, use it forever. Your recipe is ready to save and share! 🍕✨

💫 What You Learned

A function is a named recipe: function makePizza(topping){ ... } — write the steps once.
A parameter is an input slot (the word topping). Each call passes a different ingredient (an argument) like "cheese" or "pepperoni".
Calling a function = makePizza("cheese"). The function runs its steps and returns a result.
One function, MANY calls: the same recipe made cheese, pepperoni, and veggie pizzas — just by passing different toppings!
The rule lives inside the function, so changing it affects every pizza you bake — that's reusable code.
